To whom t may concern:

Be it known that I, JAMES Toni), a citiizen of the United States, residing at Sewickley, Allegheny County, Pennsylvania, have invented a new and useful Improvement in the Manufacture of Ozonized Air,' of which the following is' a full, clear, and exact description.

The present invention relates broadly to the production of so-called ozonized air and more cient y produclng an ozone constituent which is substantially constant, irrespective of temperature changes in the atmosphere. This Yresult is obtained, even though the rate of airsupply is also maintained constant.

Yl am aware that it has heretofore been proposed to provide ozonizing apparatus with means whereby the operable voltage impressed on the ozone generator 'might be increased or decreased. A

Heretofore, however, there has been no Vattempt to vary the effective voltage imenerator in accordance with variations in tile temperature of the atmosphere to thereby compensate for such changes.

As ointed out in my Patent No. 1,066,065 of lu y l, 1913, the ozone constituent produced by an ozone generator of definite characteristics decreases as the temperature ci' the atmosphere increases, and incresases as .the temperature or' the atmosphere decreases.

l' have' also discovered, as set forth in my copending application, Serial No. 567,483,

filed June, l0, 1922, that it is possible to largely compensate forthe tendency of anl ozone generator to produce an ozone cgistituent which varies with tein erat re changes by varying the eective e ectrode arealof the generator as, or in accordance with, the variations in the temperature of the atmos here,- that is, -by decreasing the edectivee ectrodearea as the temperature of the atmosphere decreases, and increasing the edective electrode area as the temperature of the atmosphere increases.

rl'he present invention is a division in part and a continuation of mycopending application, Serial No. 567,484, filed February 23, 1923, as a renewal of my application led l une 10, 1922.

By 1the present inyentiom ll edect a coin-- pensation for variations in the temperature articularly to an apparatus for ef.

vor flow for any given setting.

of the atm hereby varying the effective Y voltage whi e maintainin constant the volume of air, the electro e area and the strength of the dielectric within the ozone generator. v

In the accompanying drawings, have shown for purposes of illustration only, certain embodiments of the' present invention, it being understood that the drawings do not deinevthe limits of my. invention, as changes may be made in the construction and the operation illustrated, without departing from the spirit of the invention or the scope of my broader claims.

ln the drawings:

Figure 1 is'a ydiagrammatic'illustration of one form of apparatus for carrying out the present invention; and

Figure 2 is a similar view of a slightly modified form of apparatus.

Referring -more particularly to Figure 1 of the drawings, there is illustrated an ozone generator 2, adapted to receive the desired operating voltage from the secondary 3 of a suitable transformer.

ln order -to eect variations in the voltages delivered by the transformer, l'i'may provide the primary 4 thereof with a series or sections adapted to be successively out in or out out of circuit by a switch 5, one side of the primary l of the'transormer may re' ceive electric energy through a suitable, connection 6 from the line wire L, while the switch 5 may be electrically connected in any desired manner with -a main controlling switch 7 receiving current from the line wire L through the connection 8 andthe motor 9. y l

' By reason of this construction, it will be apparent that when the switch 7 is closed, current will flow' to the motor 9 and with the switch 5 in the position illustrated to all of the sections or the prima l..

The motor 9 may be operativey connected in an desired manner to a blower or suction' evice 10 for producing an air dow through the ozone generator 2 whichoma if desired, be positioned within a suitab e easing il. This device may be ci such construction as to produce a constant vole li, for, any reason, the temperature atmosphere varies, ll have oundsthat there will be ,a corresponding variation in v the ozone constituent produced by the oroniaer.

ldd

ofthe V tions of the Y atmosphere decreases.

In order to overcome such variations and maintain-a substantially constant ozone constituent irrespective of temperature changes, and with a constant rate of air supply, I may operate the switch 5 to cut out secand'therebyl increase the voltage output of the secondary as the temperature increases, or ma move the switch 5 to successively cut in ad itionalsections in the primary of thetransformer as the temperature of the v accordance-With temperature variations in the atmosphere by the use of a thermostatic means of any desired construction.

I have diagrammatically illustrated thi means in Figure 1 as comprising a lever 12 having a xed pivotal mounting 13 and a link connection -14 with the switch 5. The lever 12 may be normally urged in one direction by a spring 15 and may be moved in the opposite directionagainst the action of the spring by theexpansion of the expansible member of the thermostat 16.

In Figure 2 there is illustrated diagrammatically a slightly modied embodiment of the present invention in which Vfor purposes rimary 4 of'the transformer creases, substantially as describe 2. In the'r'nanufacture of so-called ozonized air, ythe step consisting of decreasing the eifective voltage delivered to an ozonizer as the temperature of the atmosphere dein approximate proportion to the ytemperature of the atmosphere, decreasing the eiective voltage as the temperature decreases and increasing the same as the tem erature in- 5. In'the manufacture of so-called oizbnized air, the step consisting in varying the effective voltage delivered to an`ozon1zer, and .v

decreasing the eieetive voltage as the temperature .decreases and increasing the ef.- ective voltage as ythe temperature increases, substantially as des'cribed. l

` 6. In the manufacture of so-called ozonized air, the step consisting in automatically varying the effective voltage delivered to an ozonizer according to the tem erature of the atmosphere, substantially as escribed.

7. In the lmaufacture lof so-called ozonized air, the step consisting in automatically varying the effective voltage delivered an ozonizer in approximatel proportion to the of conciseness -in the specification- I have Atemperature of the atmdsphere, decreasing designated parts corresponding to parts already described in connection with Figure 1 by the same reference. characters having a prime aixed thereto. In this form of invention the primary winding ltof' the transformer may comprise a single section and the desired voltage variations may be produced by the use of a variable resistance 17 in series therewith.

.It will be understood that I produce variations in the voltage impressed on the generator while maintaining within 'the same a xed dielectric whereby the eiective discharge within the generator is caused to vary. The dielectric initially utilized will have a strength suiciently high to prevent rupturing thereof when operated at the highest variations which may be delivered by the transformer connected thereto.

The advantages of the presen., invention will be obvious to those skilled in the art,

since it provides an' effective and inexpensive -method for obtalnlng an ozonlzed air of uniform character.

I claim:
